INHALING TUBE.

Application led December 4, 1919. Serial No. 342,396.

T o all whom t may concern.'

Be it known that I, WILLIAM A. PAGE, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in an Inhaling Tube, ofwhich the following is a specification.

This invention consists in an inhaling tube adapted to be utilized atone end for inhalation through the nostrils and at the other end throughthe mouth, with the important provision of opening both ends for inhalation through either and to afford suction through the medicatedabsorbent at the middle of the tube, all substantially as shown anddescribed and particularly pointed out in the claims.

In the accompanying drawings, Fig. 1 is a central sectional elevationlengthwise of the tube, and Fig. 2 is a cross section on line 2 2, Fig.1.

Fig. 3 is a plain eleva-tion of the tubel closed, and F ig. 4 is anelevation thereof with the ends sectioned and shown as open, as in use.

The article as thus shown is of comparatively small size for conveniencein carrying on the person, as in a gentlemans vest pocket or in a ladiespocket or handebag, and in addition to being small is also light inweight and of simple construction for convenience in use. Thus, the bodya may be of hard rubber, or its equivalent, and also the end caps and cl'as well as the spindle CZ, and all the said parts have specialfeatures for mutual adaptation as will now appear. For example, the bodya is tubular and has annularly reduced ends 2 shouldered about theirbase, and the end which is adapted to receive the capi Z; is slightlycontracted toward its extremity to receive the inwardly tapered cap b,which is enlarged internally to sleeve over the reduced end 2 andagainst the shoulder 3. The oversleeving portion of this capis reducedin thickness up to its shoulder 3 so as to bring its external surfaceflush with the surface of body a, and the extremity 4 thereof is taperedexternally and internally to substantially conical shape, leaving arelatively small end opening with a tapered seat adapted to receive thecone-shaped extremity 5 of the spindle and which practically constitutesa valve for the perfect closure of the said opening. The opening andclosing of the said valve is effected by rotating the said cap withinthe limits of the .inclined cam slots 6 oppositely in the said cap, andieaded pins 8, having their reduced ends permanently fixed in the end 2of body a and their heads occupying said slot and flush on the outsideserve as stops in said slots. Pins are used instead' of screws to avoidpossible vtampering with the device by removing the caps, as might occurif screws were used, and the pins are made a permanent fixture. Then asthe cap is rotated to closed position, the parts sustain the relationseen in Figs. 1` and 3, and when rotated to open position they sustainthe relation shown in Fig.` 4, and the heads of the pins rest in thestraight terminals of said slots.

The` same principle of construction and operation obtains at theopposite end of the tube a., except that at this end the cap c and thereduced end 2 of the tube are of the same size or cross section betweentheir ends and a conical or tapered hole 14 in the end of the cap isadapted to receive the conical extremity or valve 15 on the end of thespindle. Cam slots 6 and pins 8 are used in this cap like those at theother end and the two caps are independently rotatable.

The spindle d has a body portion 16 at its middle which fits somewhatlsnugly in the body of the tube andhas an annular channel or grooveabout its middle nearly the full depth thereof and a; series of bores orholes 18 axially through the standing portion of said body on both sidesof said channel open to the interior of the tube a at both ends, and thesaid channel is of a size and depth suflicient to receive a suitablefibrous absorbent 20, which may be packed therein more or less denselyand as will be most effective in retaining or holding a medicatingsolution. The said packing is introduced at the assembling of the parts,andthe medication is accomplished through the hole for the screw plug 22as may be needed.

The advisability of having both caps rotatable to open position is seennot only in the dual use they afford for medication by inhaling throughthe nostrils, or through the mouth, or either at pleasure, but whicheverend is used the other end is opened also to provide for circulation andimpregnating the air with the medicament by suction or draft through thesame, and more or Y less opening of either cap is possible by thepresent construction, the comparatively close fit of all the partsmaking provision for such use. Of course both the body a and the spindleZ remain in the relation shown, and neither is movable in respect to theother and all adjustments are in the end caps b and c, and these Withinthe limits of their respective slots 6, which have the same inclination.lhen not in use both caps are closed and the tube is thus sealed againstthe escape of any odor from the inside and the medicament is protectedagainst evaporation, which is important in an article Aof this kind.

Vhat I claim is:

l. An inhaling tube havingv annularly reduced end portions providedWithpins, Caps seated over said end portions and having in- @linedgrooves in their sides engaged on said pins and provided with axialopenings, a spindle ixed in said tube having a bored hub engaged inlsaid tube and its ends construoted to close said openings, and anabsorbent belt about said hub and exposed to the bore therein.

2. An inhaling tube adapted to have air drawn through the same, aispindle fixed therein having tapered ends and a body portion at itsmiddle With a channel about the same and a series of holes through theWalls of said channel, a belt of absorbent material fitting said channeland caps rotatably engaged on the ends of said tube having axial holesopposite the ends of said spindle.

3. As a newl article of manufacture, an inhaling tube having a tubular`body, a. cap rotatably mounted on each end of said body and providedWith an axial opening, a spindie stationary in said body constructed atits ends tov close said openings by the rotation of said caps andprovided with. a hubv between its ends engaging the Wall of Said bodyand provided with axial openings throughH the. same and an. annularchannel about the hub communicating with said openings, andabsorbentmaterial oeeupyino' said channel.
